Application filed February 17,1900- serial No- (N model!) To all whom, it may cot Loewe:

Be it known that I, JOSIAH E. NIGHTIN- GALE, a citizen of the United States, residing at High street, Danvers, in the county of Essex and State of Massachusetts, have invented new and useful Improvements in Machines for Measuring the Areas of Surfaces,

of which the following is a specification.

This invention relates to improvements in to machines for measuring the areas of surfaces,

more especially those of irregular outline, such as hides and skins, and relates particularly to improvements in the indicating device of measuringmachines of the kind 1 5 shown in the patents granted to WVilliam A.

2 5 resents a longitudinal section on the line 3 3 shown in Fig. 2. Fig. 4 represents a crosssection on the line 4 4 shown in Figs 1 and 3; and Fig. 5 represents across-section on the line 5 5, also shown in Figs. 1 and 3.

' Similar letters refer to similar parts wherever they occur on the different parts of the drawings.

The essential features of my present improvement consist in means for adjusting 5 the bracket in which the pinion and dialpointer shaft are mounted relative to the rack on the weighted arm or beam, so as to cause said pinion and rack to properly inter mesh, also in means for adjusting the posi- 40 tion of the rack relative to the said weighted arm or beam and the pinion on the dialpointer shaft for the purpose of causing the indicating device to measure correctly all variations in the area of the surfaces of the 5 hides or skins, and also in means for adj usting the bracket in which the weighted arm or beam is pivoted relative to the lever-suspension chain, so as to cause the latter to be arranged vertically in a line with and over the point of suspension on the uppermost lever in the system of yieldinglevers, and thereby to cause the machine to record accurately the areas of the surfaces to be measured.

described in the Sawyer patents above men-' tioned, on which this application is an impiovement.

In Fig. 1, A A represent the uprights of the frame of the machine, to the upper ends of which is secured the cross-bar B, which extends from one end of the machine to the other, as is common in machines of this kind. To said cross-bar is secured a bracket 0, which is longitudinally adjustable thereon, preferably by means of set-screws D D going through slotted perforations O O in said bracket and screwed into perforations in the said cross-bar, as shown. The upper end of the said bracket 0 is preferably provided with a vertical cylindrical socket O,,adapted to receive the cylindrical shank E, having an upper forked end E, in which the beam or arm F is pivoted at f, as shown. The shank E may be adjusted up or down in the socket G or slightly oscillated, so as to cause the beam or arm to be hung properly relative to the pinion on the index-pointer shaft hereinafter to be described. The said shank E after being adjusted within the socket C may be secured in such adjusted position, preferably by means of a set-screw e, as shown.

G is a balan ce-weight adj ustably secured to one end of the arm or beam F, as usual.

H is acurved metal piece longitudinally adj ustable upon the beam F and adapted to be secured thereto after being adj usted by means of a set-screw h, as shown.

On the upper portion of the curved metal piece H is located a chain-holding block I, provided with a screw 1, passing loosely through an car 72- on the curved piece H and adapted to be adjusted by means of a nut I and locked in its adjusted position by means of a suitable check-nut 1 as shown.

To the lower end of the blockI are secured the upper ends of the chains K 'K, one on each side of the beam F, and to the lower ends of said chains is attached a bail or rod tem of levers usually employed in machines of this kind. The ends of the lever M are,

pivotally connected to levers M M, and the ends of the latter are pivotally connected to o-biea-m F,as shown.

to By having the bracket G adjustable lengthwise upon the beam F .the positionof the.

chain or chains K K and rod L can be ad 3' usted so as to cause such to be arrangedperi" V pendicularly above the point of suspension 5 m,'where the lever M is hung, so as tocause :themachine to record the areas most acc urately. N is another bracket,adjustably secured upon thebeam F and is for this purpose preferably provided with slotted perfo 2o rations N N, through which thefastening screws O are inserted and afterward screwed or otherwise secured to the said beam F, as shown. The upper portion'of said bracket .N is provided, preferably, with a cylindrical 2 5 socketN, adapted to receive the cylindrical shank P, having an upper forked end P, in which the'indexpointer shaft Q is j ournaled, -19 is a vsetscrew by-means of which the- 'shankl? may be secured within the socket 3o N"after. said shank has been adjusted in the latter,geither in a-vertical or horizontal plane,

as may be desired. I

Tothe-shaft Q is secured-the pinion Q, as well as-the'indexspointerg, which is made'to indicateupon a stationary graduated dial R,

as usual. The teeth of the pinion Q mesh inthe teeth of the curved rack S, which is preferably secured in a detachable manner; to. aseg nent S, which is-pivoted at S to the S? S are screw-threaded ears or projections on the segment S, adapted to receive the set-' screws T T, bymeans of which the said-segment. S vand its rack S may be adjusted-on 5 thepivot SLrelative to the pinion Qfor'the :purpose hereinbefore stated.

In machines of this kind it is very essential that the suspension-rod L and its-chain =K shouldbe arranged perpendicularly in aline with the point of suspension mto cause the vdeviceto record the areas most accurately, andthiscan easily be accomplished by the adjustment of the bracketO on thebeam F, as stated, It is also essential that the teeth ofi-the fpi'nion Q and rack S should intermesll tionofTtherack Son .itspivotal connect-ion,

. part of the said rack to engage the pinion Q with more or less frictional resistance as compared with its other end, and thisl accomplish by adj usting the positions of the regulating-screws T T, as described.

' What I wish to secure by Letters Patent and'claim is- .1. In a machine-for measuring the areas of surfaces, an indicator device consisting in combination a cross-bar or'stationary support, abeam pivotally connected to said sup port, a rack pivotally connected to said beam I a'nd means'for adj usting said rack on its piv-' otal connection, a pinion meshing in said rrack, and havingits-shaft journaled in a bearing on said support, an index-pointer se cured to said shaft, a stationary dial; and a connecting device betweensaid beam and the system of levers comprisingpartof the measuring device, substantially as and for the pur- 2.
